    摘要： A reagent container includes a base defining a plurality of wells having openings exposed at an upper surface of the base and a tube receptacle. The plurality of wells include a first set of wells and a second set of wells. Each well of the first set of wells has an opening to a well bore and a channel in communication with the well bore. The opening has a first portion disposed over the well bore and a second portion disposed over the channel. The first portion has a larger area than the second portion. An angle defined by tangents to the inner surface of the first and second portions at a junction between the first and second portions is at least 100° and not greater than 180°. The reagent container further includes a top coupled over the top surface of the base and defining windows providing access to the openings of the plurality of wells and the tube receptacle.

    摘要： Provided is an assay cartridge capable of improving the throughput of the assay by shortening the time until the bubbles generated in the assay region disappear as compared with the prior art. The assay cartridge includes an assay strip that has, on the surface thereof, an assay region in which a color development state changes depending on whether a sample is positive or negative, an accommodating part that accommodates an amplifying liquid that amplifies the color development of the assay region, and the assay cartridge that is supplied from the accommodating part, an absorber that absorbs at least a part of the amplifying liquid which flows on the surface of the assay strip toward the assay region and has passed through the assay region.

    摘要： The immunochromatographic assay apparatus includes a loading part in which a cartridge including an assay strip having an assay region is attachably and detachably loaded, a detection unit that detects the density of the assay region, a processor configured to perform a positive-negative determination of whether the sample is positive or negative based on the density acquired from the detection unit. The processor is configured to start acquisition of the density from the detection unit from a preset time point before the density of the assay region is saturated, and perform saturation point determination of whether or not the density has reached a saturation point based on a time change of the density, and in a case where it is determined in the saturation point determination that the density has reached the saturation point, perform the positive-negative determination.
